On Wednesday July 30th The Heritage crew took a small lesson on flint knapping with Rod Johnson. Rod has been flint knapping for about 30 years and he pursued this skill because it related to his work with archeology.
After a small power point about the history and different styles of flint knapping we were given some hands on experience on how you flint knapp.
Rod also showed us the marks that are present in flint knapping that differs from regular rocks. Being able to distinguish these marks is a good skill to have when figuring out if an item is a worked artifact or just a random rock. One of the marks is called the bulb of percussion. The bulb of percussion is the part of the rock that swells into a bulb after you hit it. Following the bulb of percussion are ripples in the rock. It looks like you dropped something into a river and seeing its ripples but instead of dropping you strike the platform and instead of river it’s a rock and instead of the ripples fading it stays frozen into the rock.
